NAME¶
struct_ieee80211_channel - channel definition
SYNOPSIS¶
struct ieee80211_channel {
enum nl80211_band band;
u32 center_freq;
u16 hw_value;
u32 flags;
int max_antenna_gain;
int max_power;
int max_reg_power;
bool beacon_found;
u32 orig_flags;
int orig_mag;
int orig_mpwr;
enum nl80211_dfs_state dfs_state;
unsigned long dfs_state_entered;
unsigned int dfs_cac_ms;
};
MEMBERS¶
band
band this channel belongs to.
center_freq
center frequency in MHz
hw_value
hardware-specific value for the channel
flags
channel flags from enum ieee80211_channel_flags.
max_antenna_gain
maximum antenna gain in dBi
max_power
maximum transmission power (in dBm)
max_reg_power
maximum regulatory transmission power (in dBm)
beacon_found
helper to regulatory code to indicate when a beacon has
been found on this channel. Use regulatory_hint_found_beacon to enable
this, this is useful only on 5 GHz band.
orig_flags
channel flags at registration time, used by regulatory
code to support devices with additional restrictions
orig_mag
internal use
orig_mpwr
internal use
dfs_state
current state of this channel. Only relevant if radar is
required on this channel.
dfs_state_entered
timestamp (jiffies) when the dfs state was entered.
dfs_cac_ms
DFS CAC time in milliseconds, this is valid for DFS
channels.
DESCRIPTION¶
This structure describes a single channel for use with cfg80211.
